In October 2015, enVerid installed six HLR
® (HVAC Load Reduction) 1000B Modules on the roof of IKEA store located in Ne-tanya, Israel. The installation was done in collaboration with the HVAC company Tadiran. and in coordination with Ikea’s facility management team.
The scope of this HLR ® installation includ-ed self-service and cashier areas on the ground floor and all areas (restaurants, showrooms, and self-serving areas) on the first floor, as shown on the diagrams to the right.
Summary
IKEA’s initial installation saved 20% energy and reduced outside air consumption by 53%.

Initial Results
Energy Savings: During October 2015, initial energy monitoring and reporting were conducted. Energy savings was calculated from measured water flow, water supply and return temperature of chillers read from the Building Management S.ystem. During HLR ® ON mode, outside air volume was reduced by 53%.
In October, data shows an average energy consumption decrease of 2,204 kWh (20%) per day when HLR ® ON compared to HLR ® OFF. We expect to obtain higher energy savings over the hot summer season. enVerid and Tadiran will continue with the demonstration and will issue a full report to document the energy savings in the summer season.
Indoor Air Quality:
For the monitoring of indoor air quality (IAQ), the concentration of the contaminants of concern (i.e., aldehydes, speciated volatile organic compounds, and carbon dioxide) were measured prior to the HLR ® operation and then again after the HLR ® was operational for at least one week. Indoor air quality monitoring and testing was performed according to EPA Standards and the air samples taken on site were calibrated by an independent certified lab (Prism Analytical Technologies).
We measured six testing locations that correspond to the different areas served by each HLR ®. To obtain a good representation of the air quality in the space, we performed mobile sampling: we put IAQ instruments in a cart and relocated to different sampling locations within each testing location. An example of testing is shown in the pictures below. The pollutant concentrations database is used to show compliance with the ASHRAE Standard 62.1 indoor air quality procedure (IAQP; ASHRAE Standard 62.1, 2013).
Although the Outside Airv olume was reduced by 53%, the HLR
successfully maintained the contaminants of concern below their established threshold values. See graph below for the summary of IAQ comparison of two contaminants of concern: formaldehyde and carbon dioxide.
